Re-Imagining Linux Platforms to Meet the Needs of Cloud Service Providers


"Ogg Vorbis is an open-source and patent-free audio codec that is being developed by Xiphophorus along with several other multimedia projects (cdparanoia and Icecast, to name two). Xiphophorus is a collection of open-source, multimedia-related projects and programmers who are working to ensure that Internet multimedia standards reside in the public domain where they belong. The work on Ogg Vorbis is currently funded by iCAST, the entertainment arm of CMGI."

"Ogg Vorbis is an open standard, and this is important for a number of reasons. There are few truly open standards in the realm of digital audio. Look at Windows Media, Quicktime or RealAudio. These standards are all closed and proprietary, and because of this, none of the standards interoperate well (or at all outside of their corporate walls) with one another. When was the last time that you could play Quicktime 4 in RealPlayer or vice versa? When will Linux have Quicktime or Windows Media support? Linux and the Internet are founded on open standards, and as multimedia on the Internet and on Linux rapidly matures, the need for multimedia applications like Ogg Vorbis grows rapidly as well."

"There are two parts to Ogg Vorbis: Ogg and Vorbis. Ogg is a wrapper format, similar in some ways to Apple's Quicktime or Microsoft's Active Streaming Format. It helps you collect a group of things that belong together. For example, if you have an Ogg movie file, it might contain a Vorbis stream alongside a video stream in another codec. Or the Ogg movie file might contain ten Vorbis streams, one for each language available."
